Theory of azimuthally small-scale hydromagnetic waves in the axisymmetric magnetosphere with finite plasma pressure [PDF]
Annales Geophysicae, 1998 The structure of monochromatic MHD-waves with large azimuthal wave number m≫1 in a two-dimensional model of the magnetosphere has been investigated. A joint action of the field line curvature, finite plasma pressure, and transversal equilibrium

Longitudinal oscillations in density stratified and expanding solar waveguides
, 2012 Waves and oscillations can provide vital information about the internal structure of waveguides they propagate in. Here, we analytically investigate the effects of density and magnetic stratification on linear longitudinal magnetohydrodynamic (MHD) waves.

Recent advances in boosting interfacial bubble dynamics with external fields
Droplet, EarlyView.External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

Magnetohydrodynamic (MHD) Waves in Plasmas
مجلة كلية التربية العلمية, 2022 The model for a magnetoplasma is given by the MHD equations, so the first aim is to give a full list of MHD equations, with the criteria of their applicability for wave propagation. The validity conditions under which the MHD equations are used require the wave frequency to be, and the seven eigenvectors are obtained.

Analysis of Magnetic Fields in Inertial Alfven Wave Collisions
, 2014 Turbulence in astrophysical and space plasmas is dominated by the nonlinear interaction of counterpropagating Alfven waves. Most Alfven wave turbulence theories have been based on ideal plasma models, such as incompressible MHD, for Alfven waves at large
